As a Norwegian this is quite funny. At least the last few decades we've been super focused on not working too hard to such a degree that it's often characterized as national lazyness by the Norwegian press. If a Thursday is a national holiday it is VERY common to take Friday, and maybe Monday off too.

We look down on many countries, like the US, because they tend to overwork and prioritize work over life.

Our success, like the oil fund and high ratings, has much more to do with a series of smart efforts on building a mutually beneficial society where people trust each other, the media, businesses, the police, the government etc than just hard work. Many people from all around the work hard, but just hard work doesn't lead to good societies. In fact the mantra of "hard work" often leads to the opposite - survival of the fittest to the detriment of others.
